It is a cup that attaches to the honeycomb wall.
It has a height of 80 mm and a diameter of 60mm.
I remixed it from another model to store my coffee grinder in, but you could use it for other things as well.
I have attached the blender files that I used so that you can modify them further as you need.
The connection plate was made with this library
https://www.printables.com/model/542305-updated-openscad-library-for-hsw-attachments
with this command
include<hex_plug_library.scad>
row(connections=false) {
insert_with_plate(tolerance = .05);
insert_with_plate(tolerance = .05);
insert_with_plate(tolerance = .05);
}The author remixed this model.
